The idea is to have a single ssh-agent instance that holds all the keys. Checking and spawning of ssh-agents should be consistent now. --- ...2009-09-03-working-with-key-passphrases.textile | 23 ++++++++++++---------- 1 file changed, 13 insertions(+), 10 deletions(-) diff --git a/_posts/2009-09-03-working-with-key-passphrases.textile b/_posts/2009-09-03-working-with-key-passphrases.textile index 11fd037..604221e 100644 --- a/_posts/2009-09-03-working-with-key-passphrases.textile +++ b/_posts/2009-09-03-working-with-key-passphrases.textile @@ -36,29 +36,32 @@ h2.
